Direct contact with eyepieces is a poten-
tial transmission method for bacterial and viral
infections of the eye. Users should be made
aware of the potential risk of infection. The risk
can be kept to a minimum by using personal eye-
pieces for each individual or detachable eyecups.
1.3 Light source: Safety instructions
Protective measures of the manufacturer:
– UV protection screen in front of the object
plane prevents direct view onto the UV beams.
– The design prevents direct UV radiation on the
eyes in case of empty positions of the nose-
piece disc.
– UV filter in the observation beam paths protects
the eyes.
– Stray-light protection on the lamp housing pre-
vents irradiation of the hands.
Warning: UV radiation could damage
the eyes.
For this reason:
– never look at the light spot on the object plane
without UV protection screen.
– do not select a white, heavy reflecting back-
ground for the objective.
– Never open the lamp housing while the lamp is
switched on.
Danger of explosion, UV radiation, danger of
